Idea from #7361

• Ref: chore: generate feature flag files from shared #7361
• Components that need to be processed: sdk/metric/internal/x

Hi @flc1125 @joohnnyyu , I’m interested in this issue and noticed it hasn’t had much activity lately. If no one is actively working on it, I’d be happy to jump in and put together a PR. Thanks!

@ternua8 all yours. Thanks for checking in!

@MrAlias @flc1125 Since the x component template is not exactly the same as sdk/metric/internal/x, I’d like to confirm if it’s fine to use the template as-is, or if some modifications are expected.
